Toallwlwanitm concerm" v Be it known. t at we, Jonas Bonn and Sweden, residing at (xottenborg, Swe en,

have invented certain new and' useful Im-Z' piovementin Steam Cleansing Devices for comotive Boilers or the like, of which the following is-a specification.

In marine bor'lers'and sometimes also in stationary boilers the use ofsteam cleansing or sweepm devices is well lm'owm'for the cleansing o the tubes,=the sa1 d devices primarily' consisting of a steam supplypipe with a dischar nozzle the latter being entered into the re box or'into the smoke uptake in such-a position that the escap ng steam may act upon the tubes, either in the direction of, the draft, or contrary to such direction. In locomotive boilers where an inclined bridge 'is generally disposed m from; of part ofthe set o f tubes the chaployment of such an apparatus is rendere difficult on vaccount. of the excessive heatjprejet from being obstructed by the bridge As it is hardly pJossible for a erson to work in front of the oi-ler when dnving the locomox from. the the locomotive. The above cirtive the cleansing or sweepin 'a paratus cannot be brought into the smofie front end 0 cumstances, therefore, always necessitated the sweeping'of locomotives-to take place at intervalsiwhen the -engine was not in act ve operatiom this naturally involving a COIlSlderable loss of time, besides which the draft.

of the locomotive is reduced, particulajrl when drivin over long distances, throng the masseso grime which in the'meantime Father in the tubes.

'l lie present invention relates-tea contrivance by means of which the said difiiculties are overcome so that sweeping may take place at anytime during the run of the en ne. heinvention is principallycharacterized by this that a steam supplg pipe provided with adischarge nozzle is tted in the furnace in such wayas to enable the nozzle to be lpmwn manner,

might'be required andplaced in such a position" by means of manmuvring devices accessible in the drivers cabin, that-the esi'vie'w pf the some-of the parts bein shown in section.

comparatively narrow and "contrivance according to all: ,shown artly consists of a lever 18a taping steam will hit the tubes and enter the same, the said discharge nozzle being .also

2 is a vertical crosssection of the same part,

and Figs. 3 and 4 respectively represent a horizontal section and an elevation of the art ofthe boiler shown in Figs. 1 and 2. i .5 and- 6, which are drawn to .a-larger sea e, show two horizontal soda-ions .of a smaller part of the same boiler fitted with a steam sv'veepin device, and Fig. 7 is a plan etails according to Fig. -6,

1' de'fiignates the she! plate ofthe locomotive b 1 er, the furnace 2 being arranged within it in known manner. The furnace 2 is connected -with.the smoke box by means of an upper group of larger tubes 3 and a lower grou of smaller tubes 4. An'inclined bridge 5 in known manner prevents the fire from entering the tubes 3, 4 directly. At the one side of the furnace 2 a steam supply pipe 6 is inserted through a pipe 7 passing through the water room between,the walls1 and 2, the said pipe 'Tbeing fitted water t ght to theplates 1 and 2. The steam' supply p pe 6 1:8 rotatably and slida'bly mounted 1n a casmglfi secured to the plate 1, the said-casings. being provided with a chamber supp ied with steam from the boiler through a ipe 9. The chamber 25 communicates wit the inner side of the pipe 6 through apertures 26 in the latter when the 1pe 6 occupies the position shown in Fig. 6. At the and adjacent to the furnace the steam sup 1y pipe 6 is fitted with a discharge noz e 11. provided with a' low-throughchannel 12 which, in known ay -is shaped so as to give the escaping steam a flattened out fan-like spreading The .pipe is provided with a manoeuvring contrivance '8 reaching into the drivers cabin 10. The said manoeuvring embodiment n a pin Iii with its iforked end. 'the glg l passing thr'o h the part of the pi e 6 which is outside-of t e casing 16. The wand 21 of the pin 15 is provided with a'iblot, this slot adapted 'to be brought out of the furnace so far that it is withdrawn from direct contact being entered by a stud 27 on an arm 20. The arm 20 is secured to a rod 19 which is Mounted on the rod 13 by means of screws 23 so that the rod 19 and the rod 13 togather form a art of the manoeuvring contrivanee 8. T e screws 23 are adapted to pass through slots 24 provided in the rod 19, so that the latter may be moved relatively to the rod 13. The rod 19 is extended through the wall 10 and turned to a handle :32 on the inside of the said wall 10.

The operation of the apparatus is as follows:

Vl'hen sweeping is to be done the steam supply pipe 6 is entered into the furnace by means of the rod this rod bein adapted to swing in the manner of a lever ulcrumed in the wall of the drivers cabin. This being done; the apertures 26 of the pipe 6 are brought within the chamber 25 on the easing 16 communicating with the pipe 9 so as to cause the steam to be discharged throu h the channel 12 of the nozzle 11 against t e tubes, as is diagrammaticall shown b full lines in Fig. 1. Through t e manipu ation of the handle 22 the pin 15, 21and the pipe 6 may be turned from within the drivers cabin by sliding the rod 19, 20 to and fro so that the steam et will sweep over all of the tubes 3 and 4 in turn, or only over part of 41cm, as may be desired. The sweeping having been done, the pipe 6 is drawnin so far within the pipe 7 by swinging of the rod 13, that the edge 17 of a cap enclosing the nozzle 11 will abut againsta sleeve 18 pro- Ecting from the casing 16 into the pipe 7. y this withdrawal 0 the pipe 6 with its discharge nozzle 11 these parts are protected against any damage from the fire and the hot ases in the furnace. Through the with rawal of the pipe 6 within the pipe 7 the steam a ertures 26 will be moved out of range of t e chamber 25 gsee Fig, 5) and the supply of steam is here y discontinued without a separate shut-01f valve having to be manipulated.

By means of the manoeuvring contrivance 8 formed by the rods 13 and 19 the whole apparatus niay be easily and conveniently operated, and all of the tubes, or only a part thereof, may be swept over bv the steam et by turning the apparatus through an an is less than 180.

1e device shown in the drawings and described hereinbefore evidently only repre sents an embodiment of the invention which.

may be modified in its details without de by other means than hereinbefore described, provided the characteristic feature of the apparatus is such, that it may, when acted upon from within the drivers cabin, also during the run of the locomotive, send the steam jet against the whole of the set of tubes, or only against a part thereof, so as to force the grime out of the tubes.
